15 clean sheets in 38 appearances (39% of games). Playing behind an upper-table side (4th of 20) means a more protected goal, so the read is about command and distribution as much as raw shut-outs.

Strengths

  • Availability. On the pitch for 100% of available minutes — a dependable presence in the XI.

Watch points

  • Few red flags. No obvious weaknesses in the current-season profile — consistency is the next test.

Outlook

With a Rating of 49.3, Osako carries the 2nd-highest potential of the goalkeepers in the J1 League (top 11%). A near ever-present keeper carrying the gloves this season. In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.
